Numerical Determination of the Mean Value of an Elasticity Tensor by Integration over the Rotation Group with Haar Measure

Kossi Atchonouglo, Claude Vallee, Zi-Qiang Feng & Jamal Chaoufi · Journal of Advances in Mathematics and Computer Science · 2015

Let A be a 3D symmetric elasticity tensor not necessary isotropic. If μ is an invariant measure on SO(3), then μ is a convex combinaison of the Haar measure. The nearest isotropic elasticity tensor is obtained by integrating the tensor A on the rotation group SO(3). For the numer...

Efficient Quantization Method for Biometric Fingerprint Image Compression

B. S. Emmanuel, M. B. Mu’azu, S. M. Sani & S. Garba · Journal of Advances in Mathematics and Computer Science · 2015

The choice of quantization method and the requirement to achieve a trade-off between compressed image quality and degradation are very crucial in the overall performance of a lossy image compression algorithm. In this paper, uniform and non-uniform scalar quantization schemes of...

A Fourth-Order Nonlinear Conjugate Gradient Method in Equality Constrained Optimization

Nwaeze Emmanuel, Okpala Mmaduabuchi & Ozoigbo Gerald · Journal of Advances in Mathematics and Computer Science · 2015

This paper presents a fourth-order nonlinear conjugate gradient method in equality constrained optimization. The idea is to transform the constrained problem into unconstrained type through the Lagrange multipliers scheme. Using four terms of Taylor series development, we approxi...

A Note on Semi-Compatible Maps and Occasionally Weakly Compatible Maps in Non-archimedean Menger PM-Space

Arihant Jain, Abhishek Sharma & Basant Chaudhary · Journal of Advances in Mathematics and Computer Science · 2015

The concept of semi-compatible and occasionally weakly compatible mappings is used to prove a common fixed point theorem. The theorem thus obtained is a generalization of the result of Cho et al. [10] in a non-Archimedean Menger PM-space.

A Global Indicator for Measuring the Efficiency of Machine Learning Classifier Based on Multi-Criteria Approach

Hegazy Zaher & Mohamed Abdullah · Journal of Advances in Mathematics and Computer Science · 2015

The main challenge that faces any researcher in the field of machine learning is determining the quality of an indicator used for measuring the efficiency of classifier techniques. This issue based on Multiple-Criteria Decision Making (MCDM) has not been tackled by any researcher...

Longest Waiting Time in the Coupon Collector’s Problem

C. Brennan, J. Kariv & A. Knopfmacher · Journal of Advances in Mathematics and Computer Science · 2015

The coupon collector’s problem is a classical problem usually solved by summing independent but not identically distributed geometric random variables. These geometric random variables represent waiting times for the j-th coupon for j = 1, 2,..... In this paper we address the que...

On Projectively Related Kropina Metric

S. K. Narasimha Murthy, B. C. Chethana & G. N. Latha Kumari · Journal of Advances in Mathematics and Computer Science · 2015

In the present paper, we study curvature properties of projectively flat Kropina metric and prove that two Finsler metrics re projectively related if and only if they have thesame Douglas tensors. Further we showed that corresponding Riemannian metrics are projectively related.

Detecting Plagiarism in Arabic E-Learning Using Text Mining

Farahat F. Farahat, Aziza S. Asem, Mahmoud A. Zaher & Ahmed M. Fahiem · Journal of Advances in Mathematics and Computer Science · 2015

Being a growing problem, plagiarism is generally defined as a “literary theft” and an “academic dishonesty” in the literature, and it is really has to be well-informed on this topic to prevent the problem and stick to the ethical principles. Due to the hug of digital libraries an...
